I had originally planned on using 6-7 layers of 1/4" Luan plywood with fiberglass between each sheet, but the cost of the epoxy resin and the fiberglass started to really add up. Not to mention the weight of the core was going to be astronomical. Instead I chose marine plywood, which was expensive, but not as staggering as the other option.
In the photo above I used a piece of Luan to make the template for the core.
Above, I am tracing the template to the marine plywood.
Here is the core clamped together so that I could sand the edges flush. I also sanded all sides of all 3 pieces. A layer of 1.5oz. mat will be laminated between each piece.
I spent a very long day putting the new core in the transom of the boat. Don't ever let anyone tell you this is an easy task. Its messy and you have to work fast! I managed to get the 3 pieces of marine plywood laid into the boat and then the inner skin was laid-up. The inner skin is composed of : 1808 DB, 1.5oz mat, 18oz Roven Woven, 1.5oz mat, & 1808 DB
I didn't manage to tie the whole thing into the sides and bottom of the hull. I'll have to do some grinding to flatten things out along the edges. Then I'll lay-up some tabbing along the sides and hull bottom.
I also have to make a new skin that is flush with the existing outer skin. I'll tackle this project once I finish the interior work mentioned above.
The work accomplished today required 4 gallons of 4:1 epoxy resin.
